Thank you for your reply.
It is one shape per layer, with a starting point keyframe and an endpoint (positioning). I know you can do the same thing using the path masking but this just works the same way.
When I input loopOut () it only loops once and then stops.
This will need to go into Powerpoint presentation also, so i am hoping I can convert this into a Gif as my manager would like to input copy over it (its a chart after all). I did try to do this in Photoshop as a gif but proved quite tricky.
Thanks
